- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Dinosaur National Monument protects two different things in two states: the Quarry district near Jensen, Utah, where about 1,500 Jurassic dinosaur bones still sit in the rock face, and the Canyon district in Colorado, where the Green and Yampa rivers cut 600 m deep gorges with petroglyphs and homesteads. The districts are about 2 hours apart by road and share one entrance fee. Most visitors come for the bone wall; the canyons reward those with a full day and a high-clearance vehicle.

Why go
- The Quarry Exhibit Hall is the only place in the US where you can touch a Jurassic bone still embedded in the rock wall.
- Two visitor centres, two states, one ticket: the Utah side is bones, the Colorado side is canyons.
- Harpers Corner and the Tour of the Tilted Rocks are self-guided drives you can do in your own car.
- Petroglyphs and the Josie Bassett Morris homestead add 10,000 years of human history to the fossil story.
